As the United States takes bold strides toward a clean energy future, the electric power industry is bracing for a surge in electricity demand unlike anything it has witnessed before. Driven by the accelerating electrification of transportation, buildings, and industry, experts predict that US electricity consumption could triple over the next two decades.

At the forefront of this transformation are the transportation and building sectors. In the transportation segment, electric vehicle (EV) sales are soaring, with US EV sales expected to reach nearly 9% of new car sales in 2023 and surpass the one million cars per year milestone. Powered by new federal incentives, plummeting battery costs, and a growing selection of affordable EV models, this trend is poised to intensify in the coming years.

Similarly, the building sector is undergoing its own electrification revolution, with residential and commercial properties increasingly transitioning to electric heat pumps and water heaters in lieu of fossil-fueled systems. In 2022, monthly shipments of electric heat pumps and water heaters surpassed those of gas furnaces and water heaters for the first time, and 25 governors have committed to installing 20 million electric heat pumps in their states by 2030.

While the industrial segment may be the slowest to electrify, experts anticipate that electricity demand for this sector could still grow at a modest yet steady pace, reaching over 1,070 terawatt hours (TWh) by 2035. As power companies grapple with the prospect of this accelerating electricity demand, they are diligently analyzing their resource mixes and infrastructure investment needs to ensure they can reliably and affordably serve these emerging loads while meeting ambitious decarbonization goals.

Fortifying the Grid: Tackling Reliability Challenges in the Face of Change

As the electric power industry prepares for a potential tripling of electricity demand, ensuring grid reliability has become a paramount concern. Extreme weather events, the growing intermittency of renewable energy sources, and the retirement of traditional baseload power plants have all contributed to heightened resource adequacy risks across North America.

In recent years, the North American Electric Reliability Corporation (NERC) has warned that up to two-thirds of the continent could face energy shortfalls during periods of peak demand or severe weather conditions. The rolling blackouts in California during the 2020 heatwave and the prolonged outages in Texas during the 2021 winter storm Uri serve as stark reminders of the vulnerabilities that lie ahead.

To address these reliability challenges, power companies are exploring a range of innovative approaches, including:

Harnessing Distributed Energy Resources (DERs) in Virtual Power Plants (VPPs): By aggregating flexible resources such as rooftop solar, energy storage, and demand response, VPPs can provide valuable grid-balancing services and help meet spikes in electricity demand.
Improving Distribution System Planning (DSP): By enhancing their visibility and planning capabilities at the distribution level, utilities can better forecast load growth, identify capacity constraints, and deploy cost-effective solutions to maintain reliability.
Integrating DSP with Bulk System Planning: By aligning distribution-level planning with the forward-looking integrated resource planning (IRP) process for the bulk power system, utilities can develop a more holistic view of their future resource needs and reliability requirements.

These strategies, combined with a continued focus on maintaining adequate generation capacity, promise to be essential tools in the industry’s arsenal as it navigates the complex transition to a more electrified, renewable-powered grid.

Confronting the Specter of Water Scarcity: Safeguarding Power Production in a Drying Climate

As the western United States grapples with an unprecedented drought, the electric power sector is facing its own water-related challenges. Prolonged dry conditions are threatening the output of both hydroelectric and thermal power plants, which rely on abundant water resources for cooling and generation.

Hydroelectric facilities, which account for approximately 6% of US electricity generation, have seen their output decline by more than 9% year-over-year in the first eight months of 2023, with the Northwest region experiencing a 24% drop. Meanwhile, thermal power plants, including coal, nuclear, and natural gas-fired units, are struggling to maintain efficiency as they draw hotter water from depleted reservoirs and face environmental restrictions on hot water discharge.

The implications of this water crisis extend beyond immediate operational disruptions. As hydroelectric generation dwindles, it is often replaced by gas-fired power, which can increase carbon emissions and make it more difficult for states and utilities to meet their decarbonization goals. Furthermore, reports warn that the two largest US hydroelectric reservoirs, Lake Mead and Lake Powell, could soon reach “dead pool status,” rendering them incapable of producing power.

In response, the power industry is exploring a range of strategies to reduce its water consumption and adapt to the realities of a drying climate. These include:

Shifting toward less water-intensive generation technologies: The growth of wind and solar power, which do not require cooling water, is helping to reduce the sector’s overall water footprint.
Utilizing alternative water sources: Power plants are increasingly turning to brackish water, greywater, or recycled water for cooling instead of relying on scarce freshwater resources.
Improving water efficiency: Advancements in cooling system technologies and operational practices are helping to optimize water use and minimize water-related impacts on power generation.

As the industry continues to grapple with the water-energy nexus, a more holistic, cross-sectoral approach to sustainable water management may be necessary to ensure the long-term reliability and resilience of the electric grid.

Funding the Energy Transition: Navigating the Complexities of Capital Expenditure

This unprecedented level of investment, driven by the need to upgrade aging infrastructure, integrate renewable energy, and prepare for rising electricity demand, is putting significant pressure on utilities and their customers.

Utilities are employing a variety of strategies to fund these critical initiatives, including:

Rate Increases: Seeking regulatory approval for rate hikes to pass on the costs of grid modernization and clean energy investments to customers. However, after a 25% average residential customer bill increase over the past five years, some regulators may be more inclined to challenge and limit further rate increases.
Alternative Funding Sources: Tapping into grants, loans, and tax credits from federal and state programs made available under the Infrastructure Investment and Jobs Act (IIJA) and the Inflation Reduction Act (IRA). These funding sources are expected to provide up to $94 billion in support for grid infrastructure, clean energy supply chains, and electrification initiatives.
Business Transformation and Asset Optimization: Driving operational efficiencies through digital technologies and selling non-core assets to free up capital for grid investments. Many utilities are also exploring innovative business models, such as selling renewable energy and resilience services directly to corporate customers.
Debt and Equity Markets: Raising funds through debt and equity offerings, although rising interest rates and weakening utility stock performance have made this option less attractive in recent times.

As utilities navigate this complex financial landscape, they must strike a delicate balance between modernizing the grid, meeting decarbonization goals, and keeping electricity affordable for their customers. The influx of federal funding and the industry’s embrace of innovative financing strategies offer promising paths forward, but the challenges of the energy transition remain formidable.
